The Genus Lueddemannia

Reichb.f. 1854

The genus Lueddemannia was established by Heinrich Gustav Reichenbach ("Rchb.f." 1824-1889), who published Lueddemannia pescatorei in Bonplandia ii, page 281 (1854). It was named for M. Lueddemann.

They are large-growing epiphytic orchids with only a few species known from the South America Andes (Peru to Venezuela). It is possible that the three species listed as valid by IPNI are all the same, and the genus may be monotypic.
Gerlach (1999) places Lueddemannia within the "Acineta-Verwandtschaftsgruppe," allied with Acineta, Lacaena, and Vasqueziella, within the larger Stanhopinae Alliance.

The plants have ovoid, ridged pseudobulbs, each bearing 2-4 large, pleated leaves. The inflorescences begin from the base of the pseudobulbs and are always pendant, with fleshy, showy flowers hanging downward ("nodding") on a simple raceme.

They seem to require intermediate to cool conditions. Viateur Boutot translated the following from Hervé Canals (1994) Stanhopea et genres allies, p. 55:
"cool conditions, in a pot, in a mix of very fibrous peat, well drained.
Water well when the plant is actively growing. During the winter, the
plants may be grown in cool conditions and given as much light as possible while the waterings are reduced. Repot when new shoots emerge."
